About JotTools

JotTools is a growing collection of free, fast, privacy-friendly online tools for PDFs, images, text, conversions, generators, calculators and developer tasks. The goal is simple: the everyday utility you need, in one place, without sign-ups, paywalls, or uploading your files to a stranger's server.

How it works

Almost every tool runs entirely in your browser. When you merge a PDF, resize an image, format JSON or generate a password, the work happens on your own device using modern web technology, so your files never leave your computer. That makes the tools fast, available offline after first load, and private by design. A few tools download an open-source processing engine on first use, but even then your content is processed locally.

Who builds it

JotTools is built and maintained by Bilgetek, the team behind the BulkPro desktop application for batch file processing. We build practical software for writers, students, designers, developers and everyday users. JotTools is the free, browser-based companion to that work, and when you need to process hundreds of files at once, BulkPro picks up where the browser's limits begin.

Why you can trust it

• Private: your data is processed locally and not stored on our servers.
• Free: no account, no trial, no hidden limits, supported by unobtrusive ads.
• Transparent: read our Privacy Policy and Terms.
• Improving: we add tools and refine existing ones regularly.
